Integrated battery tester boosts pack formation and grading
Compared to conventional technology, the AD8452 provides 50% more channels in the same amount of space, adding capacity and increasing battery production throughput.
The device uses switching technology that recycles the energy from the battery while discharging and delivers 10 times more accuracy than conventional switching solutions. The higher accuracy allows for more uniform cells within battery packs and contributes to longer living batteries in applications such as electric vehicles.
Using the AD8452 also enhances the safety of manufacturing processes by providing better detection and monitoring to help prevent over and undercharging which can lead to battery failures.
The device reduces the bill of material (BoM) by 50% for charging/discharging boards and potential system cost savings of approximately 20%. System simulating demonstration boards will be available and can enable lower R&D engineering cost and shorter time to market for test equipment manufacturers. This enables energy recycling battery formation/grading for systems of 20Ah or less with up to 95% power efficiency using precise measurement of current and voltage better than 0.02% over 10⁰C temperature change.
The AD8452 is available now for $5.85 in a 48 Lead LQFP package.
